Abstract
This study was designed to evaluate the possible effect of two different psychophysical techniques on lingual vibrotactile sensory thresholds. Ten subjects were tested using the ascending psychophysical method of limits and the forced-choice signal detection technique of threshold assessment. Results indicated that both techniques provided consistent, reliable threshold data, but the forced-choice method yielded lower (more sensitive) lingual sensory thresholds. Results are discussed with respect to the appropriate utilization of both testing procedures.
